The built-in MC booster of 4.2P SP adopts OPA2277 to design a new circuit to solve the industry technical problems of low-frequency interference and low-frequency dynamics of vinyl. The full channel uses OPA1602 to take into account the sound bottom and indicators. The RAII circuit is designed to reject feedback mode and use advanced The key components of the attenuation mode network are all capacitors and resistors with customized values ​​(the attenuation type does not have dynamic compression compared to the feedback type, and the RAII curve is accurate but requires accurate components). The cartridge loads of Mc and MM can also be adjusted separately.
The built-in crossover technology adopts the crossover circuit technology developed by the manufacturer for high-end models, aiming to strive for excellence in different applications. In order to adapt to the usage environment in Hong Kong, a parametric volume adjustment function is specially added, and each of the 3-band EQ Each frequency point has 4 frequency selections, and the Q value can also be adjusted. In order to achieve a flat and equal-sounding listening experience at low volumes late at night, four frequency curve adjustments, as well as low-frequency boost and attenuation, are specially designed. The above professional adjustments may seem complicated, but each defaut setting is thoughtfully designed.
The design of the built-in power amplifier circuit is a Class D circuit developed by the manufacturer for 10 years, and its tone is extremely close to that of a Class A amplifier.
4.2P SP not only has outstanding sound but also eye-catching design. The use of hexagonal golden gongs adds a touch of luxury to the speaker, while the prominent gong design creates a strong sense of strength. The open paint process of rosewood veneer makes this speaker visually impressive;
The speaker is a product specially supplied by Danish brand Wavecor for 4.2p: 22mm tweeter unit voice coil design optimization:
Aluminum field stabilizing ring reduces distortion
Copper-clad aluminum coils improve efficiency and dynamic performance
Precision craftsmanship:
Special cavity design reduces distortion
It is suitable for listening in a larger space and does not need to be placed against the wall; it not only focuses on LP but does not develop trendy BT, but also focuses on transmitting the highest quality 5.0BT lossless solution.
Geddon Electronics, which never compromises on sound quality, strives to perfect the machine. All audio wiring of the machine is custom-made by a professional manufacturer in Germany. The power cable also uses the top line base of Goffen imported from Switzerland;
All functions can be controlled using the dedicated App on your mobile phone, which is convenient, intuitive and high-end.
